The Diver Collection is an homage to what is arguably the most iconic category in the history of watches. A technical watch, the Diver Automatic 42mm blends functionality typical of a dive watch with elevated details and design found in all Jack Mason designs. The high gloss dial features superluminova markers. The agonized aluminum top ring and ceramic bezel are paired with a stainless steel case and bracelet. The Diver Automatic 42mm JM-D301-001 is elevated with sapphire crystal while the 42mm case is compatible with any 22mm Jack Mason strap. At 30ATM the screw down crown is etched with a Texas lone star while the casebook is etched with a Diver’s helmet—a nod to Jack Mason’s roots and the historical place of the diver watch in the history of timepieces.
